背景概述在安防行业视频监控领域,网络化、高清化、智能化是近段时间及未来的必然发展趋势。人们不断追求更高清晰度的视频体验,体现高清的一个重要因素就是摄像机的分辨率,随着视频监控技术的发展,分辨率经历了从入门高清720P到全高清1080P再到超高清4K的发展阶段。按照国际通讯联盟(ITU)定义的标准,4K的分辨率为3840×2160,长宽比为16:9。标准的4K分辨率下,像素点总数可以达到800万,而以往的FHD(全高清1080P)是指1920×1080,是200万级别像素点,前
Background Overview In the field of video surveillance in the security industry, networking, high definition and intelligence are the inevitable trends in recent times and in the future. People continue to pursue higher definition video experience, an important factor in the realization of high definition is the resolution of the camera. With the development of video surveillance technology, the resolution has gone from entry HD 720P to full HD 1080P to ultra HD 4K development stage. According to the standard defined by the International Telecommunications Union (ITU), 4K has a resolution of 3840 × 2160 and an aspect ratio of 16: 9. The standard 4K resolution, the total number of pixels can reach 8 million, while the previous FHD (Full HD 1080P) refers to 1920 × 1080, is 200 million pixels, the former
